Percent means parts out of 100
24%=24/100=2.4/10=0.24/1=0.24
'of' means multiply
24% of 80=0.24 times 80=19.2

A school district signs a contract to purchase 50 of the electric typewriters (normally selling for $129.95) from ABC at a quant
zaharov [31]

The price the school district pays for each typewriter is $106.56.

<h3>What is the price for each typewriter?</h3>

A quantity discount is the discount given for bulk purchases. It reduces the purchase price of a good or service.

Total purchase price of the typewriters before the discount = (50 x 129.95) = 6,497.50

Total purchase price of the typewriters after the discount = (100 - 18) x 6,497.50

= $5,327.95

Purchase price of one typewriter = $5,327.95 / 50 = $106.56

How would I find angle B for this bridge? What formula would I use?
astraxan [27]
The bridge attached is drawn according to given dimensions, and it doesn't look right.  Please double check the given dimensions.

Calculations:
Horizontal part of bottom chord below the 70 degree triangle 
= 15.1*cos(70) = 5.16  (which is a major prt of the 6.3 units.
Height of vertical pieces DF and EH
= 15.1*sin(70) = 14.19
Note that structurally, DF and EH do not help in reducing stress on the bridge, since they are perpendicular to the bottom chord.

Therefore 
angle B = atan(14.19/(6.3-5.16))=85.41 degrees

I believe the whole geometry does not look right, esthetically, and structurally, since the compression members are much longer than the tension members in the middle.  (The vertical members carry no force.) 
If  you can review the input data, or post a new question, I will be glad to help.

Please answer the following
natulia [17]

Answer:

cot∅ = (-2√30)/7.

Step-by-step explanation:

Given the value of csc∅ = -13/7 and ∅ is in quad III.

We know y = r sin∅ and r > 0. So csc∅ = r/y = -13/7 = 13/(-7).

It means y = -7, r = 13.

We know x² + y² = r².

x² = r² - y²

x² = (13)² - (-7)² = 169 - 49 = 120.

x = √120 = 2√30.

we know cot∅ = x/y = (2√30)/(-7) = (-2√30)/7.

Hence, cot∅ = (-2√30)/7.
